Is LinkedIn Lying?

My job title is pretty unique, made up to be honest.  Often I get emails from LinkedIn saying things like: “27 FounderBoss jobs were filled on LinkedIn recently.”

I just find it hard to believe that anyone actually ever recruits for a ‘FounderBoss’.  Even more hard when I click on the link within the email to see current jobs listed and it says there are none.

So is LinkedIn lying and how ethical, or not, is it to do this kind of thing?
